Large-scale studies of the mycocomplex of Eurasian Arctic were carried out, with the model group of macromycetes – clavarioid fungi as an example. The species composition was revealed in all longitudinal sectors and latitudinal subzones; its comparative analysis was carries out. It was established that the clavarioid life form is best adapted to the extremal psychrophilic conditions of Arctic among other groups of aphyllophorous fungi. It is demonstrated that ocean-side sectors are most rich, while the continental ones are essentially scanty. The distribution of the species composition of fungi agrees with the similar distribution for flowering plants, especially for hemicryptophytes. The annual amount of precipitation appears as the leading climatic factor. The established differences allow one to subdivide the Eurasian Arctic into four mycogeographic regions: Atlantic (European), Siberian, Chukotka (Bering) region, and the High Arctic.
